Relationship between serum magnesium levels and intracranial aneurysm risk

Takeaway

  • Higher serum magnesium (Mg) concentrations were associated with reduced risk of intracranial aneurysm and aneurysmal subarachnoid hemorrhage.

Why this matters

  • Serum Mg is implicated in blood pressure (BP) regulation and vascular endothelium function, but it was previously unknown whether it affects the risk of intracranial aneurysm and subarachnoid hemorrhage.

  • Results of this study indicate a beneficial role of higher Mg for prevention of cerebrovascular and cardiovascular diseases and may have future treatment implications.
